I don't understand this argument. I've heard high school teachers decree it as a mathematical truth before.

Do we all agree absolute value is a function from reals to reals? If so, the absolute value of any real number is nonnegative. It can be zero or any positive numbers.

Case closed, right?

It's like taking a signed int and turning it into an unsigned int though. It doesn't become positive it just loses its sign.
